Hi All,
I would like to build a PLC trainer/simulator, I have Digital Input and Output, Analaog Input and Output (0-10 VDC, 4-20mA),RTD module, and High Speed module.
On the front panel PLC simulator there are:
1)Many push buttons that connected to digital input
2)Many pilot lamps that connected to digital output
3)Potensiometers that gives source 0-10VDC and 4-20 mA connected to Analog input
4)Digital displays that will show up value from analog output (example digital Amperemeter will show value when potensiometer 4-20mA was turned or Digital Voltmeter will displaying 0-10VDC when potensiometer 0-10VDC was turned).
5)PT 100 sensor that connected to RTD module
6)Encoder that connected to High speed module(simulating rpm motor with turning encoder by hand)
My question:
What is the architecture to showing temperature value and speed/rpm using digital displays?
Is it good to use Scaling Meter(Digital Display) that connected to analog output (this display will make scaling from 4-20mA to engineering unit)?
Your advice would be appreciated, thanks!
